"U.S. counterterrorism officials have determined that several extremist groups, including Ansar al-Sharia, took part in last year's attack. ... But on the first anniversary of the attack, there is not 'anyone in custody who can tell us' specifics, including when, where and by whom the plot was hatched, and whether the Sept. 11 date was selected in advance or was a last-minute choice of opportunity, a counterterrorism official said. 'That is a huge gap,' said the official, who spoke on the condition of anonymity to discuss the investigation. 'What we lack is a source of information that puts us where we need to be.' "

"The Justice Department has indicted suspects. Intelligence officials have a general idea of where they are hiding. And the military has a contingency plan to snatch them if that becomes necessary. But the fledgling Libyan government, which has little to no control over significant parts of the country, like Benghazi and eastern Libya, has rebuffed the Obama administration's efforts to arrest the suspects."

Just how dangerous things remain in Benghazi was underscored Wednesday with the news that a car bomb exploded there near a building that "once housed the U.S. consulate," according to The Associated Press. There were no serious injuries.
